FIELD: information technology.
SUBSTANCE: invention relates to wireless communication and, more specifically, to notification in a wireless communication system on reception quality for high-speed batch communication using adaptive modulation and planning. The device provides for increase in system capacity through reduction of crosstalk noise with respect to other wireless communication devices. In the device the section for extracting information extracts information which indicates the number of CQI-indicators, contained in control information. The section for measuring reception quality measures reception quality of each subcarrier within the transmission frequency band. The CQI formation section generates CQI-indicators for some high reception quality subcarriers within the communication frequency band. A multiplexer multiplexes CQI-indictors, information on the number of subcarriers which form CQI-indicators, ACK or NACK signals. The SC selection section then selects the number of subcarriers from the base station device, with high reception quality, assigned using information for CQI quality.
EFFECT: increased information capacity, and reduction of power consumption through reduction of the control signal value.
